M81133 Type 1/24V Mechanical Linear Drive Unit (Short Stroke, Raymarine)

The Raymarine Type 1/24V linear drive offers all the benefits of the standard Type 1 (12V) in a configuration for 24-volt onboard electrical systems. It is intended for boats up to ~11 tons and is especially useful for vessels with dedicated 24V infrastructure or those seeking lower autopilot current draw. This drive retains the short 300 mm stroke, providing quick rudder movement and quiet operation. Compared to the 12V version, the 24V motor operates at half the current for the same power, which can extend component life and reduce heat.

Use cases and benefits:

• Boats with 24V systems: well-suited for sailing and motor yachts (~35–45 ft) equipped with 24V batteries – allows direct connection without converters
• Pair with ACU-400: since the Type 1 (24V) requires higher voltage, using the ACU-400 is recommended as it supports both 12V and 24V drives
• Full functionality: retains all features – strong thrust, rapid rudder response (~11 sec hard-over), and the clutch for automatic disengagement to ensure safe manual steering
• Raymarine reliability: built with the same high-quality components, ensuring durability and resistance to marine conditions. Installation follows standard linear drive procedures and is best performed by a professional for optimal results
